Combining speed, grip, durability, and shape, Spitfire Formula Four 101d Classics Skateboard Wheels have been a long-standing favorite for a reason. They're just really really good. Arguably the best, if you're the type to argue about skateboard wheels. Get some and find out!

Classic Shape – The #1 shape in skateboarding worldwide - proven for speed and control.

101a Durometer – Some of the hardest wheels you can get. Ideal for advanced skaters who skate fast, power slide often, and want to avoid flat-spotting.

Formula Four Urethane – Formula Four urethane is unlike any other. Both in the streets and under high-speed stress tests in Spitfire's lab, Formula Four wheels retained more material, coned less and kept their original shapes and sizes longer than any other wheel.

Smooth Anti-Stick Slide – Gives a consistent and fast smooth slide all the way through. Slide with confidence knowing your wheels won't skip or catch mid-slide.
